BERT LEON, OF TOLEDO, OHIO, ASSIGNOR OF ONE-HALF TO WILLARD A. SHERER, OF TOLEDO, OHIO.

EMBALMERS INJEGTING AND ASPIRATING APPARATUS.

T 0 all whom it may concern:

Be it known that I, BERT LEON, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Embalniers Injecting and Aspirating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in apparatus used. by enibalmers for injecting and aspirating fluids into and from dead bodies. Heretofore in the art to which my invention relates the apparatus employed for this purpose comprised an aspirating jar, a trocar and its flexible connection with the aspirating jar, an air-pump having two nipples, one for forcing air and the other for withdrawing it, and a flexible connection leading between the aspirating jar and one or the other of the pump nipples. The last mentioned flexible connection is adapted to connect with one nipple of the pump when the apparatus is employed for aspirating and with the other nipple when it is employed for injecting. This arrangement has required frequent and inconvenient changing of the connection by the operator from one nipple to the other and since the tubing employed is made of soft rubber and as the operators hands are invariably covered with vaseline which is destructive to rubber, the tubing where it is attached to the pump nipples rapidly deteriorates and softens and therefore becomes unfit for use.

To obviate the frequent changing of the pump connection from one nipple of the pump to the other my invention is constructed, the only operation required to change the apparatus herein described from an aspirator to an injector being the simple turning of a valve stem.

In carrying out my invention I employ the novel combination, arrangement and details of construction hereinafter shown, described and claimed.

In the accompanying drawings, Figure 1 illustrates my invention used in connection with the ordinary aspirating jar, a trocar, and the connections therebetw'een; Fig. 2 is an enlarged sectional detail showing the valve device for controlling the air employed to operate the aspirating jar; Fig. 3 is a Specification of Letters Patent.

perspective of the valve stem removed from the valve body.

Referring to the details, Fig. 1, 1 indicates the well known form of aspirating jar or bottle, the same having the usual air-tight closure 2, the stopper 3, the hard rubber tubes 4 and 5 extending through the stopper, and the connection 6 leading downwardly frorr. the inner end of the tube 5 to a point net the bottom of the jar.

indicates the usual flexible or rubber connection carrying the trocar 8 at the end thereof, the other end connecting with the tube 5. In like manner the flexible connection 9 leads from the air-pump 10 to the upper end of the tube 4.

The arrangement of the apparatus thus far, when used with an ordinary pump, and the operation of the same, is old and well known in the art.

To provide a simple means for controlling the air delivered or taken from the aspirating jar I have constructed a valve device which by a simple manipulation either causes the air from the pump to be forced into the aspirating jar or withdrawn therefrom. The pump 10 has a piston (not shown) which is actuated by the ring 11 at the end of the piston-rod, the air as the piston is operated being drawn into the pump cylinder 12 through the passage 13 and be ing forced out of the cylinder through the passage 14, reversely arranged soft rubber checks 15 and 16 of well known and ordinary construction preventing the passage of the air in a direction contrary to that indicated by the arrows.

17 is a rotatable valve stem having a handle or operating head 18, and this valve stem is arranged crosswise so as to intersect both passages 13 and 14.

19 and 20 are transversely arranged openings or perforations in the valve stem, the same being at substantially right angles to each other and so disposed that one air passage connects with the pump cylinder while the other is closed, it being impossible for both air passages to be open at the same time.

21 and 22 are pump nipples at the outer ends of the passages 13 and 14 to which are connected short flexible tubes 23 and 24, united at 24 by means of a Y-connection which in turn is connected with the tube leading to the aspirating jar.

Patented Oct. 18, 1910.

25 is a groove in the Valve-stem adapted to serve as a vent connecting with the inner portion of the passage 13 to admit air to the pump cylinder when the valve is turned to close the passage 13; and in like manner there is a groove 26 which serves as a vent connecting with the inner end of the passage 14 when the valve is turned to close the passage 14.

It will be noted that the vent which connects with the passage 13 will be out of connection with the passage 13 when the valve stem is turned to cause the air to be drawn into the pump from the aspirating jar. In like manner the vent connecting with the passage 14: will not connect with said passage when the valve stem is turned to cause the air to be forced from the pump into the aspirating jar.

Thus it is seen that by a simple quarter turn of the valve stem in one direction the air will be drawn from the aspirating jar by the operation of the pump and by a 1 arter turn in the opposite direction the air will be forced into the aspirating jar.

the checks, the vents being opened and 1 closed with the valve device so that when one is open the other is closed, substantially as described.

In testimony whereof, I hereunto aflix my signature, in presence of two witnesses.

BERT LEON.
